【Abstract】 The mathematics model of semi-active quarter -c oach suspension was founded. According to the characteristics of time-varying o f parameters and time-delay of the semi-active suspension, a new intelligent c ontrol-FCMAC algorithm based on Fuzzy logic control techniques was presented and used to perform online control of semi-active suspension, both information ret rieval and learning rules were described by algebraic equations.The results of e xperiment showed,excited by sinusoidal input and random disturbance input,FCMAC control strategy can reduce the value of mean square root of vertical accelerati on of semi-active suspension system to be lower 26 19%和24 96% in compared w ith the open-loop.The further investigation of this technique was pointed out.更多还原
